Abstract

The transport system has a pneumatic feed line, to which the cigarette filters are fed individually from a supply reservoir, via axis parallel reception pockets (2) in a rotary transfer wheel (1). The pockets are indexed past an ejection zone, in which the filter is displaced along its axis by pressurised air, for input to the pneumatic line. The longitudinal movement of the filter in the ejection zone is monitored, with a fault signal supplied when the filter fails to be ejected from the pocket in a given time interval, pref. defined between the entry of the pocket into the ejection zone and the exit of the pocket from the ejection zone.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 und eine Vorrichtung nach dem Oberbegriff des Anspruchs 7.The invention relates to a method according to the preamble of claim 1 and an apparatus according to the preamble of claim 7.

Der Transport der Filter von der Filterherstellung zur Weiterverarbeitung beispielsweise in einer Filteransetzmaschine erfolgt in der Regel über eine pneumatische Förderleitung, die eingangsseitig an eine Sendestation und ausgangsseitig an eine mit dem Magazin der Weiterverarbeitungsmaschine verbundene Empfangsstation angeschlossen ist. In der Sendestation werden die Filterstäbe in aufeinanderfolgenden Aufnahmen eines rotierendes Überführungsförderers (Sendetrommel) queraxial aus einem Vorrat in eine Abschußposition gebracht, in der sie mit der pneumatischen Förderleitung fluchten. In der Abschußposition werden sie mittels Druckluft längsaxial in die Förderleitung bewegt, in der sie dann pneumatisch zur Empfangsstation bei der Weiterverarbeitungsmaschine gefördert werden. Während der längsaxialen Bewegung eines Filterstabes aus der Aufnahme in die Förderleitung rotiert der Überführungsförderer weiter, so daß der betreffende Filterstab gleichzeitig queraxial bewegt wird. Um ein Einklemmen der Filter zwischen dem rotierenden Überführungsförderer und der stationären Mündung der pneumatischen Förderleitung zu vermeiden, hat die Abschußzone in Umlaufrichtung des Überführungsförderers eine Ausdehnung, die auf die axiale und die queraxiale Geschwindigkeit der Filter beim Abschuß abgestimmt ist. Die Mündung der pneumatischen Förderleitung ist dementsprechend aufgeweitet und läuft trichterförmig auf das Förderrohr zu (GB 2 068 325 A). Diese GB 2 068 325 A beschreibt ein pneumatisches Fördersystem, das fünf Filterherstellmaschinen über pneumatische Förderleitungen mit fünf Magazingruppen von Filterverarbeitungsmaschinen verbindet. Die Förderleitungen verbinden dabei paarweise zwei Sendestationen der oben beschriebenen Art mit einem Magazin einer Verarbeitungsmaschine. Dadurch wird ein Magazin jeweils über zwei Förderleitungen beschickt, was eine erhebliche Verbesserung der Versorgungssicherheit der Magazine mit Filtern bedeutet. Dieses System weist eine Reihe von Sensoren zum Erfassen von Fehlerzuständen und zum Erzeugen von Fehlersignalen auf. Damit wird kontrolliert, ob der Dichtschuh oder Dichtklotz geöffnet wird, ob die Kupplung wegen Überlastung ausrückt, ob der Vorrat im Magazin ergänzt wird, ob Stäbe in die Förderleitung eintreten oder ob in der Förderleitung ein Rückstau entsteht.The transport of the filters from filter production to further processing, for example in A filter attachment machine is usually carried out via a pneumatic delivery line on the input side to a transmitting station and on the output side to one with the magazine of the Processing machine connected receiving station is connected. In the Transmitting station, the filter rods are rotating in successive shots Transfer conveyor (transmission drum) transaxially from a supply to a launch position brought, in which they are aligned with the pneumatic conveyor line. In the launch position they are moved longitudinally axially into the delivery line using compressed air, in which they are then pneumatically conveyed to the receiving station at the processing machine. During the axial movement of a filter rod from the holder into the delivery line the transfer conveyor continues to rotate, so that the filter rod in question at the same time is moved axially. To pinch the filter between the rotating transfer conveyor and to avoid the stationary mouth of the pneumatic delivery line, the launch zone has an extension in the direction of rotation of the transfer conveyor, on the axial and cross-axial speed of the filters at launch is coordinated. The mouth of the pneumatic delivery line has been expanded accordingly and runs funnel-shaped towards the conveyor pipe (GB 2 068 325 A). This GB 2 068 325 A describes a pneumatic conveyor system that uses five filter manufacturing machines pneumatic conveyor lines with five magazine groups of filter processing machines connects. The conveyor lines connect two transmission stations in pairs above described type with a magazine of a processing machine. This will make a Magazine fed via two conveyor lines each, which is a significant improvement the security of supply of the magazines with filters means. This system has one Series of sensors for detecting fault conditions and for generating fault signals on. This controls whether the sealing shoe or sealing block is opened, whether the Coupling disengages due to overload, whether the stock in the magazine is replenished, whether rods in enter the delivery line or whether there is a backlog in the delivery line.

Bei ordnungsgemäßem Betrieb einer Sendestation hat ein Filter seine Aufnahme im Überführungsförderer verlassen, wenn diese Aufnahme sich aus der Abschußzone hinausbewegt, so daß der Überführungsförderer die nächste Aufnahme ungehindert in die Abschußzone bewegen kann.When a transmitting station is operating properly, a filter is accommodated in the transfer conveyor leave when this shot moves out of the launch zone, so that the transfer conveyor unhindered the next intake in the launch zone can move.

Bleibt ein Filter beim Abschuß zurück, so daß er seine Aufnahme nicht vollständig verläßt, während sie in der Abschußzone liegt, so kommt es zur Kollision, bei der der Filter zwischen der stationären Mündung der Förderleitung und dem rotierenden Überführungsförderer eingeklemmt wird. Da sich der Überführungsförderer mit hoher Geschwindigkeit bewegt und da er stirnseitig zur stationären Mündung der Förderleitung eine hohe Scherkraft auf den eingeklemmten Filter ausübt, kann dieser teilweise abgeschert werden, wobei ein Teil des Filters in die Förderleitung gelangt und der andere in der Aufnahme des Überführungsförderers zurückbleibt. Das führt zu einer Störung, die bei stillstehender Einrichtung behoben werden muß. Die GB 2 068 325 spricht dieses Problem weder an noch bietet sie eine Lösung dafür.If a filter remains when it is fired, so that it does not completely leave its holder, while it is in the launch zone, the filter collides between the stationary mouth of the conveyor line and the rotating transfer conveyor is pinched. Because the transfer conveyor is moving at high speed moves and because it has a high shear force on the face of the stationary mouth of the delivery line exerted on the pinched filter, this can be partially sheared off, whereby part of the filter gets into the conveyor line and the other in the receiving of the transfer conveyor remains. This leads to a malfunction that occurs when the facility is at a standstill must be remedied. GB 2 068 325 neither addresses nor offers this problem a solution for it.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs beschriebenen Art weiter zu verbessern. Insbesondere soll verhindert werden, daß abgescherte Teile eines Filters durch die pneumatische Förderleitung in den weiteren Produktionsprozeß gelangen und dort größere Störungen verursachen.The invention has for its object a method and a device of the beginning to further improve the described type. In particular, the aim is to prevent sheared off Parts of a filter through the pneumatic conveyor line in the further production process get there and cause major interference.

Bei einem Verfahren der eingangs angegebenen Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß während der Bewegung der Aufnahme durch die Abschußzone die längsaxiale Bewegung des Filters aus der Aufnahme in die Förderleitung überwacht wird und daß ein Störsignal erzeugt wird, sofern ein Filter die betreffende Aufnahme innerhalb eines vorgegebenen Zeitintervalls nicht vollständig verlassen hat. Beim Auftreten eines Störsignals wird sofort automatisch die queraxiale Bewegung des Förderers angehalten. In a method of the type specified at the outset, this object is achieved according to the invention solved in that the movement of the recording through the launch zone longitudinal axial movement of the filter from the intake into the delivery line is monitored and that an interference signal is generated if a filter within the recording in question has not completely left a predetermined time interval. When an interference signal occurs immediately the transverse axial movement of the conveyor stopped.

In weiterer Fortbildung der Erfindung werden der Eintritt einer Aufnahme in die Abschußzone und ihr Austritt aus der Abschußzone erfaßt. Der Zeitpunkt des Eintritts gibt den Beginn und der Zeitpunkt des Austritts das Ende des Zeitintervalls vor, in welchem ein Filter beim Abschuß seine Aufnahme in den Überführungsförderer verlassen haben muß, um den fehlerfreien Transport des Filters aus der Aufnahme in die Förderleitung zu gewährleisten. Gemäß einer bevorzugten Ausführungsform des Verfahrens nach der Erfindung werden beim Abschuß eines Filters nacheinander der Übergang des vorderen und des hinteren Filterendes aus der Aufnahme in die Förderleitung erfaßt und entsprechende Übergangssignale gebildet, und es wird ein Störsignal gebildet, wenn nicht die Zeitpunkte beider Übergangssignale innerhalb des für den Abschuß vorgegebenen Zeitintervalls liegen. Dies ist eine besonders praktikable Methode, um die längsaxiale Bewegung des Filters beim Abschuß in die Förderleitung mit seiner queraxialen Bewegung durch die Abschußzone zu vergleichen und auftretende Fehler und entstehende Störungen sofort zu erfassen. Das Anhalten des Förderers geschieht, bevor ein nicht vollständig in die Förderleitung eingetretener Filter von der rotierenden Sendetrommel abgeschert werden kann. Um einen eingeklemmten Filter freizugeben, wird die Sendetrommel nach dem Anhalten vorzugsweise etwas zurückgedreht. Der Filter kann dann leicht aus dem Übergangsbereich entfernt werden. So wird vermieden, daß Filterfragmente durch die Förderleitung in den weiteren Produktionsprozeß gelangen. Die Ansprüche 4 und 5 enthalten Maßnahmen zur Störungsbeseitigung, mit denen erreicht wird, daß beim Abschuß hängengebliebene Filter schnell und sicher aus der Fördereinrichtung entfernt werden.In a further development of the invention, the entry of a Admission to the launch zone and exit from the launch zone detected. The time of entry gives the start and the time of exit before the end of the time interval, in which a filter on launching its inclusion in the transfer conveyor must have left the error-free Transport the filter from the intake to the delivery line guarantee. According to a preferred embodiment of the Method according to the invention when firing a filter successively the transition of the front and the rear End of filter from the intake in the delivery line and corresponding transition signals are formed, and there is an interference signal formed if not the times of both transition signals within the time interval specified for the launch lie. This is a particularly practical way to the longitudinal axial movement of the filter when fired into the delivery line with its transverse axial movement through the launch zone to compare and occurring errors and arising Record faults immediately. The Stopping the conveyor happens before one is not complete filter that entered the delivery line from the rotating one Transmission drum can be sheared off. To get a jammed To release filters, the transmitter drum will stop after stopping preferably turned back a little. The filter can then be easily be removed from the transition area. This will avoid that filter fragments through the delivery line in the further Production process. Claims 4 and 5 contain Troubleshooting measures to achieve that filters stuck when fired quickly and safely be removed from the conveyor.

Bei einer Vorrichtung der eingangs angegebenen Art wird die der Erfindung zugrunde liegende Aufgabe mit den kennzeichnenden Merkmalen von Anspruch 6 gelöst.In a device of the type specified in the object underlying the invention solved with the characterizing features of claim 6.

Fortbildungen und vorteilhafte Ausgestaltungen der Vorrichtung nach der Erfindung sind in den Unteransprüchen 7 bis 15 angegeben. Dabei enthalten die Ansprüche 7 und 8 bevorzugte Anordnungen der Überwachungsmittel, mit denen die längsaxiale Bewegung der Filter aus den Aufnahmen in die Förderleitung überwacht wird. Die Anordnung der Überwachungsmittel im Dichtklotz ist besonders vorteilhaft, weil sie auf diese Weise sehr genau in den Übergangsbereich zwischen der rotierenden Sendetrommel und der Mündung der Förderleitung eingebaut werden kann. Die Ansprüche 9 bis 11 enthalten Merkmale einer Ausgestaltung der Vorrichtung, mit der die Bewegung der einzelnen Aufnahmen durch die Abschußzone erfaßt und das für die längsaxiale Bewegung der Filterstäbe beim Abschuß zur Verfügung stehende Zeitintervall vorgegeben wird. Die Ansprüche 12 bis 15 betreffen Merkmale der erfindungsgemäß vorgeschlagenen Vorricntung, die eine vorteilhafte Nutzung der auftretenden Störsignale ermöglichen. Damit wird das Abscheren unzulänglich abgeschossener Filterstäbe vermieden und es wird erreicht, daß im Übergang zwischen dem Überführungsförderer und der Mündung der Förderleitung steckengebliebene Filter automatisch entfernt werden.Training and advantageous refinements of the device according to the invention are specified in subclaims 7 to 15. Claims 7 and 8 contain preferred arrangements of the monitoring means by which the longitudinal axial movement the filter from the recordings in the delivery line is monitored becomes. The arrangement of the monitoring means in the sealing block is particularly beneficial because it is very accurate in this way in the transition area between the rotating transmission drum and the mouth of the delivery line can be installed. The Claims 9 to 11 contain features of an embodiment of the Device with which the movement of the individual recordings through the launch zone and that for the axial movement the time interval available for the filter rods during firing is specified. Claims 12 to 15 relate to Features of the device proposed according to the invention, the enable advantageous use of the interference signals that occur. This makes shearing insufficiently shot Filter rods avoided and it is achieved that in the transition between the transfer conveyor and the mouth of the conveyor line stuck filters are automatically removed.

Der wesentliche Vorteil der Erfindung besteht darin, daß in der Sendestation entstehende Störungen sofort erfaßt werden und ihre Behebung automatisch erfolgen kann. Dabei ist durch die Rückdrehung des Überführungsförderers bei einer auftretenden Störung dafür gesorgt, daß ein zwischen dem rotierenden Überführungsförderer und der stationären Mündung der Leitung eingeklemmter Filter freigegeben wird und ohne Mühe ausgeblasen werden kann. Die schnelle Störungserkennung und -beseitigung gewährleistet eine hohe Transferrate der pneumatischen Förderanordnung. Dabei ist sichergestellt, daß keine abgescherten Filterteile in die Förderleitung gelangen und den Betrieb der nachfolgenden Maschinen stören. Das wird mit geringem technischem Aufwand erreicht. The main advantage of the invention is that in disturbances occurring at the transmitting station can be detected immediately and they can be remedied automatically. It is through the return rotation of the transfer conveyor when it occurs Disorder ensured that a rotating between the Transfer conveyor and the stationary mouth of the line jammed filter is released and easily blown out can be. The quick detection and elimination of faults ensures a high transfer rate of the pneumatic Funding arrangement. This ensures that none are sheared off Filter parts get into the delivery line and the operation of the following machines. That will be with little technical effort achieved.

Die in den Figuren 1 und 2 als Ausführungsbeispiel der Erfindung dargestellte Fördervorrichtung weist einen Überführungsförderer in Gestalt einer Vorder- oder Sendetrommel 1 auf, die mit Aufnahmemulden 2 für Filterstäbe 3 versehen ist. Die mit Saugbohrungen 4 versehenen sowie von Stegen 6 begrenzten Aufnahmemulden 2, im folgenden auch kurz Aufnahmen genannt, verlaufen parallel zur Drehachse 7 der Fördertrommel 1 und sind radial nach außen offen. Die Fördertrommel 1 ist von einem Motor 8 über Zahnräder 9 und 11 mittels einer Welle 12 in Richtung eines Pfeiles 13 kontinuierlich antreibbar. Die Fördertrommel 1 grenzt an ihrer Oberseite an ein Filterstabmagazin 14 mit vorderen und hinteren Begrenzungswänden 16 und 17 an, wo die Aufnahmen einen Entnahmebereich 18 durchlaufen. Hier nehmen die Aufnahmen 2 nacheinander achsparallel orientierte Filterstäbe aus dem Magazin 14 auf und transportieren sie queraxial in Pfeilrichtung 13 in eine an der Unterseite der Fördertrommel 1 angeordnete Abschußzone Z. Diese Abschußzone Z fluchtet längsaxial mit einer in einem Steuerring 19 vorgesehenen Mündung 22 einer pneumatischen Förderleitung 21.The in Figures 1 and 2 as an embodiment of the invention Conveying device shown has a transfer conveyor in the form of a front or transmission drum 1, the is provided with receiving troughs 2 for filter rods 3. With Suction holes 4 provided and limited by webs 6 Receiving troughs 2, also referred to as shots below, run parallel to the axis of rotation 7 of the conveyor drum 1 and are open radially outwards. The conveyor drum 1 is from a motor 8 via gears 9 and 11 by means of a shaft 12 continuously drivable in the direction of an arrow 13. The Conveyor drum 1 borders a filter rod magazine on its upper side 14 with front and rear boundary walls 16 and 17 where the recordings pass through a removal area 18. Here, the recordings 2 are oriented one after the other axially parallel Open filter rods from magazine 14 and transport them them transversely axially in the direction of arrow 13 into one on the underside the delivery zone 1 arranged launch zone Z. This launch zone Z is aligned axially with one in a control ring 19 provided mouth 22 of a pneumatic conveyor line 21.

Im Bereich der Abschußzone Z sind die Aufnahmen 2 der Fördertrommel 1 mit einem Dichtklotz 23 radial nach außen zur Umgebung hin verschlossen. Der Dichtklotz weist eine der kreisbogenförmigen Bahn der Fördertrommel 1 angepaßte Dichtfläche 24 auf und erstreckt sich am Umfang der Fördertrommel 1 entlang über die der Abschußzone Z benachbarten Aufnahmen 2 hinweg. Im angestellten Zustand stützt sich der Dichtklotz 23 ausschließlich an seinen beiden Enden mit seiner Dichtfläche 24 dichtend an zwei konzentrisch zur Fördertrommel 1 angeordneten ortsfesten Stützbuchsen 19 und 26 ab, deren Außenradius dem Radius der Dichtfläche 24 entspricht, jedoch geringfügig größer ist als der Außenradius der Fördertrommel 1. Auf diese Weise ergibt sich ein Spiel und damit eine berührungsfreie Anstellung zwischen der durch die Stege 6 gebildeten Trommelumfangsfläche und der Dichtfläche 24 des Dichtklotzes 23. Die vordere Stützbuchse 19 ist als Steuerring ausgebildet, in welchem eine mit einer Unterdruckquelle 27 verbundene und stirnseitig in einen Steuerschlitz 28 mündende Unterdruckleitung 29 verläuft. Der Steuerschlitz 28 korrespondiert mit in der Fördertrommel 1 achsparallel verlaufenden Saugluftbohrungen 31 für die Unterdruckversorgung der Saugbohrungen 4 in den Aufnahmen 2.In the area of the launch zone Z are the receptacles 2 of the conveyor drum 1 with a sealing block 23 radially outwards to the surroundings locked up. The sealing block has one of the circular arc Path of the conveyor drum 1 adapted sealing surface 24th and extends along the circumference of the conveyor drum 1 over the shooting zone 2 adjacent to the shooting zone 2. in the employed state, the sealing block 23 is supported exclusively sealing at its two ends with its sealing surface 24 on two stationary arranged concentrically to the conveyor drum 1 Support bushings 19 and 26, the outer radius of the radius corresponds to the sealing surface 24, but is slightly larger than the outer radius of the conveyor drum 1. This gives a game and thus a non-contact employment between the drum peripheral surface formed by the webs 6 and the sealing surface 24 of the sealing block 23. The front support bush 19 is designed as a control ring, in which one with a vacuum source 27 connected and the front into one Control slot 28 opening vacuum line 29 runs. The Control slot 28 corresponds to in the conveyor drum 1 Axially parallel suction air bores 31 for the vacuum supply of the suction bores 4 in the receptacles 2.

Die Welle 12 der Fördertrommel 1 1 ist durch die Stützbuchsen 19 und 26 hindurchgeführt und außerhalb der Stützbuchsen in ortsfesten Gehäusewänden 32 und 33 radial spielfrei gelagert. Die Stützbuchsen 19 und 26 selbst tragen über Zugtraversen 34 eine stationäre Montageplatte 36. Die Montageplatte nimmt zwei vertikal angeordnete Parallelführungen 37 für die Bewegung des Dichtklotzes 23 sowie zwei Druckluftzylinder 38 für zwei Druckluftkolben 39 zur vertikalen Auf- und Abbewegung des Dichtklotzes 23 auf.The shaft 12 of the conveyor drum 1 1 is through the support bushings 19th and 26 passed through and outside the support bushings in fixed Housing walls 32 and 33 mounted radially without play. The Support bushings 19 and 26 themselves carry a 34 via traverse members stationary mounting plate 36. The mounting plate takes two vertically arranged parallel guides 37 for the movement of the Sealing block 23 and two compressed air cylinders 38 for two compressed air pistons 39 for vertical up and down movement of the sealing block 23 on.

Der Dichtklotz 23 ist im gezeigten Ausführungsbeispiel zweiteilig ausgebildet. Er besteht aus einem an die äußere Form der Fördertrommel 1 angepaßten Dichtkörper 41 und einem Tragkörper 42. Der Tragkörper 42 ist gleichzeitig als Versorgungsplatte ausgebildet, in welcher eine mit einer Druckquelle 43 verbundene Druckluftleitung 44 verläuft. Zum Einleiten der Druckluft aus der Druckluftleitung 44 in die in der Abschußzone Z befindliche Aufnahme 2 der Fördertrommel 1 sind eine Querbohrung 46 im Dichtkörper 41 sowie Steuerschlitze 47 in einem Steuerflansch 48 der Fördertrommel 1 vorgesehen. Die Fördertrommel 1 weist für jede Aufnahme 2 einen separaten Steuerschlitz 47 auf, der mit dieser über eine achsparallele Bohrung 49 verbunden ist. Die Druckluft gelangt also aus der Druckquelle 43 über eine Anschlußleitung 51, durch die Druckluftleitung 44, die Querbohrung 46 und den Steuerschlitz 47, der der gerade in der Abschußzone Z befindlichen Aufnahme 2 zugeordnet ist, durch die achsparallele Bohrung 49 als Schußoder Förderluft in die zur Mündung 22 der pneumatischen Förderleitung ausgerichtete Aufnahme 2.The sealing block 23 is in two parts in the embodiment shown educated. It consists of an external shape the conveyor drum 1 adapted sealing body 41 and a support body 42. The support body 42 is also a supply plate in which one with a pressure source 43 connected compressed air line 44 runs. To initiate the Compressed air from the compressed air line 44 into the in the launch zone Z located 2 of the conveyor drum 1 are a Cross bore 46 in the sealing body 41 and control slots 47 in a control flange 48 of the conveyor drum 1 is provided. The Conveyor drum 1 has a separate one for each receptacle 2 Control slot 47 on that with an axially parallel Bore 49 is connected. The compressed air comes out of the Pressure source 43 via a connecting line 51, through the compressed air line 44, the transverse bore 46 and the control slot 47, that of the receptacle 2 that is currently in the launch zone Z is assigned through the axially parallel bore 49 as a shot or Conveying air into the mouth 22 of the pneumatic conveying line aligned recording 2.

Im Übergangsbereich zwischen der stromabwärtigen Stirnseite der rotierenden Fördertrommel 1 und dem stationären Steuerring 19 ist im Dichtkörper 41 des Dichtklotzes 23 ein Sensor 52 beispielsweise in Gestalt einer Reflexionslichtschranke, angeordnet, der die Bewegung eines Filterstabes 3 während des Abschusses in die Förderleitung 21 erfaßt. Dieser Sensor 52 ist, wie Figur 5 zeigt, mit einer Steueranordnung 53 verbunden, bei der es sich um die Maschinensteuerung handeln kann.In the transition area between the downstream end face the rotating conveyor drum 1 and the stationary control ring 19 is a sensor 52 in the sealing body 41 of the sealing block 23 for example in the form of a reflection light barrier, arranged, the movement of a filter rod 3 during the Shot in the delivery line 21 detected. This sensor 52 5, is connected to a control arrangement 53, which can be the machine control.

Der Fördertrommel 1 sind, wie in Figur 2 schematisch als Ausführungsbeispiel dargestellt, zwei Lagedetektoren 54 und 56, beispielsweise in Gestalt von Näherungsinitiatoren, zugeordnet, die ebenfalls im Dichtklotz integriert sein können Die Lagedetektoren 54 und 56 sind gemäß Figur 5 ebenfalls an die Steueranordnung 53 angeschlossen.The conveyor drum 1 are, as in Figure 2 schematically as an embodiment shown, two position detectors 54 and 56, for example in the form of proximity initiators, which can also be integrated in the sealing block Position detectors 54 and 56 are also in accordance with FIG Control arrangement 53 connected.

Figur 1 zeigt im Bereich des Eintrittsendes der Förderleitung 21 einen mit der Druckluftquelle verbundenen Druckluftanschluß 57, der zum Einleiten von Rückblasluft in die Förderleitung dient.Figure 1 shows in the area of the inlet end of the conveyor line 21 a compressed air connection connected to the compressed air source 57, for introducing blow-back air into the delivery line serves.

Figur 1 zeigt den Dichtklotz in seiner Arbeitsposition, in der seine Dichtfläche 24 an den Stützbuchsen 19 und 26 anliegt und dadurch die in der Abschußzone Z befindlichen Aufnahmen 2 der Fördertrommel 1 nach außen abdichtet. Mit einer gestrichelten Linie 58 ist die untere Position, die Wartungsposition, des Dichtklotzes 23 angedeutet. Auf die Dichtfläche des in die Wartungsposition abgesenkten Dichtklotzes ist eine Reinigungsdüse 59 ausgerichtet, die ebenfalls mit der Druckquelle 43 verbunden ist.Figure 1 shows the sealing block in its working position, in the its sealing surface 24 rests on the support bushings 19 and 26 and thereby the recordings 2 located in the launch zone Z Seals conveyor drum 1 to the outside. With a dashed line Line 58 is the bottom position, the maintenance position, of the Sealing block 23 indicated. On the sealing surface of the in the Maintenance position of the lowered sealing block is a cleaning nozzle 59 aligned with the pressure source 43 connected is.

Wie die Figur 5 zeigt, sind der Förderluftanschluß 51, der Druckluftanschluß 57 und die Reinigungsdüse 59 über Ventile 61 bis 63 mit der Druckluftquelle verbunden, damit die entsprechende Druckluftzufuhr steuerbar ist. Es sei darauf hingewiesen, daß elektrische Verbindungsleitungen in dem Schema der Figur 5 mit einer einfachen Linie und pneumatische Leitungen mit Doppellinien gekennzeichnet sind. Die frei endenden Pfeile an den Ventilen 61 bis 63 stellen die Verbindungen zu den Verbrauchern 51, 57 und 59 dar.As FIG. 5 shows, the conveying air connection 51 is the Compressed air connection 57 and the cleaning nozzle 59 via valves 61 to 63 connected to the compressed air source, so that the corresponding Compressed air supply is controllable. It should be noted that electrical connection lines in the scheme of Figure 5 with a simple line and pneumatic lines are marked with double lines. The free ending arrows at valves 61 to 63 make the connections to the Consumers 51, 57 and 59.

Wird die Fördervorrichtung in Gang gesetzt, so wird der Dichtklotz 23 aus seiner beispielsweise aus Reinigungsgründen unteren Wartungsposition 58 in seine Arbeitsposition angehoben, in der seine Dichtfläche, wie in den Figuren 1 und 2 gezeigt, an den Stützbuchsen 19 und 26 dichtend anliegt. Hierzu werden die Druckluftzylinder 38 betätigt, so daß die Druckstempel 39 den Dichtklotz 23 gegen die Stützbuchsen aufwärts bewegen. Die Zugtraversen 34 fangen dabei die auf die Stützbuchsen 19 und 26 ausgeübten Druck- und Biegekräfte auf und verspannen das System in sich. Wegen des geringeren Trommeldurchmessers der Fördertrommel 1 verbleibt dabei zwischen der Umfangsfläche der Fördertrommel 1 und dem Dichtklotz 23 ein definierter Freiraum, so daß ein reibungs- und damit verschleißfreier Betrieb der Fördervorrichtung möglich ist.If the conveyor device is started, the sealing block becomes 23 from its lower, for example for cleaning reasons Maintenance position 58 raised to its working position, in which its sealing surface, as shown in FIGS. 1 and 2, bears sealingly against the support bushings 19 and 26. To do this the air cylinder 38 actuated so that the pressure stamp 39th move the sealing block 23 upwards against the support bushings. The Zugtraversen 34 catch the support bushings 19 and 26 applied pressure and bending forces and brace the System in itself. Because of the smaller drum diameter Conveyor drum 1 remains between the peripheral surface of the Conveyor drum 1 and the sealing block 23 a defined free space, so that smooth and therefore wear-free operation of the Conveyor device is possible.

Während des Betriebs übernimmt die über die Welle 12 mit konstanter Drehzahl angetriebene Fördertrommel 1 in dem Entnahmebereich 18 Filterstäbe 3 aus dem Magazin 14 in ihre Aufnahmemulden 2, in denen sie mit der durch die Saugluftbohrungen 4, die achsparallelen Bohrungen 31, den Steuerschlitz 28, die Unterdruckleitung 29 von der Unterdruckquelle 27 angelegten Saugluft festgehalten werden. Treten die achsparallelen Bohrungen 31 der Fördertrommel 1 bei der Drehung in Förderrichtung 13 aus dem Winkelbereich des Steuerschlitzes 28 aus, so bewirkt die Fliehkraft, daß die Filterstäbe sich an die äußere Begrenzung der Aufnahmen 2 anlegen und an dieser entlang bewegt werden. Diese äußere Begrenzung wird oberhalb des Dichtklotzes von einer Abdeckplatte 64 und im Bereich des Dichtklotzes von dessen Dichtfläche 24 gebildet. In der Darstellung der Figur 2 sind nur in den Aufnahmen Filter 3 dargestellt, während die im Vorrat 14 enthaltenen Filter weggelassen wurden. Die Filterstäbe 3 werden in den Aufnahmen 2 von der Fördertrommel 1 aus dem Entnahmebereich 18 in die Abschußzone Z überführt, in welcher die Filterstäbe mit der Förderleitung fluchten. Fluchtet der Filterstab mit der pneumatischen Förderleitung 21 bzw. mit deren stationärer Mündung 22, so wird aus der Druckluftquelle 43 durch die Leitungen 51 und 44 sowie durch die Querbohrung 46 und den betreffenden Steuerschlitz 47 Druckluft zu der mit der Förderleitung fluchtenden Aufnahme 2 zugeführt, welche den darin befindlichen Filterstab 3 in Richtung eines Pfeiles 66 axial aus der Aufnahme in die Förderleitung bewegt. Da sich die Fördertrommel während dieser längsaxialen Bewegung der Filterstäbe 3 weiterdreht, werden die Filterstäbe gleichzeitig also auch queraxial bewegt. Um ihnen dennoch einen störungsfreien Eintritt in die Förderleitung zu ermöglichen, ist die Mündung 22 der Förderleitung 21 in Richtung der queraxialen Bewegung aufgeweitet, was in den Figuren 2 bis 4 erkennbar ist.During operation, it takes over the shaft 12 with constant Speed driven conveyor drum 1 in the removal area 18 filter rods 3 from the magazine 14 in their receiving troughs 2, in which they with the through the suction air holes 4, the axially parallel bores 31, the control slot 28, the Vacuum line 29 created by the vacuum source 27 Suction air are held. Enter the axially parallel holes 31 of the conveyor drum 1 when rotating in the conveying direction 13 from the angular range of the control slot 28, so causes the centrifugal force that the filter rods to the outer Set up the limit of the recordings 2 and move along them become. This outer boundary is above the sealing block from a cover plate 64 and in the area of the sealing block from whose sealing surface 24 is formed. In the illustration in FIG. 2 are only shown in the filter 3 recordings, while the im Stock 14 contained filters were omitted. The filter rods 3 are in the receptacles 2 from the conveyor drum 1 the removal area 18 transferred to the launch zone Z, in which align the filter rods with the delivery line. Flees the filter rod with the pneumatic delivery line 21 or with its stationary mouth 22, the compressed air source 43 through the lines 51 and 44 and through the transverse bore 46 and the relevant control slot 47 compressed air the receptacle 2 aligned with the delivery line, which the filter rod 3 located therein in the direction of a Arrow 66 moves axially from the receptacle into the delivery line. As the conveyor drum moves during this longitudinal axial movement the filter rods 3 continues to rotate, the filter rods are simultaneously thus also moved axially. To give them one anyway enable trouble-free entry into the delivery line, is the mouth 22 of the delivery line 21 in the direction of the transverse axial Movement expanded, which can be seen in Figures 2 to 4 is.

Figur 2 zeigt schematisch einen Schnitt etwa entlang der Linie B-B der Figur 1. Die Figuren 3 und 4 zeigen vergrößerte Ausschnitte desselben Querschnitts im Bereich der Abschußzone Z. Figure 2 shows schematically a section approximately along the line B-B of Figure 1. Figures 3 and 4 show enlarged sections of the same cross-section in the area of the launch zone Z.

In der Figur 2 ist der Schnitt durch die Fördertrommel 1 an zwei Stellen ausgebrochen, so daß dort der Blick auf die Stirnseite der Stützbuchse bzw. des Steuerrings 19 frei wird. Im oberen Teil wird auf diese Weise ein Stück des Steuerschlitzes 28 sichtbar, der zum Zuführen der Saugluft mit den Saugluftbohrungen 31 in der Fördertrommel 1 korrespondiert. Im unteren ausgebrochenen Bereich der Trommel ist die in der Stützbuchse 19 vorgesehene Mündungsöffnung 67 der pneumatischen Förderleitung zu erkennen. Gestrichelt ist in dieser Figur die gerade mit dieser Mündungsöffnung 67 fluchtende Aufnahme 2 des Förderers angedeutet, in welcher ein in die Förderleitung abzuschießender Filterstab zu sehen ist. Dabei stellt die rechte gestrichelte Linie 68 die hintere Flankenfläche des vorangehenden Steges und die linke gestrichelte Linie 69 die vordere Flankenfläche des nachfolgenden Steges 6 dar.In FIG. 2, the section through the conveyor drum 1 is on two places have broken out so that there is a view of the Front side of the support bush or the control ring 19 is free. In this way, a piece of the control slot becomes in the upper part 28 visible, the for supplying the suction air with the Suction air holes 31 in the conveyor drum 1 corresponds. in the lower broken out area of the drum is the one in the Support bushing 19 provided opening 67 of the pneumatic Recognize the delivery line. The figure is dashed the receptacle just aligned with this mouth opening 67 2 of the conveyor indicated, in which one in the delivery line filter rod to be fired can be seen. The right dashed line 68 the rear flank surface of the preceding web and the left dashed line 69 the front flank surface of the subsequent web 6.

Während des Betriebes der Fördervorrichtung gilt, daß der Abschuß eines Filterstabes 3 aus einer Aufnahme 2 des Förderers beginnen kann, wenn die Aufnahme relativ zur Mündungsöffnung 67 der pneumatischen Förderleitung die in Figur 3 gezeigte relative Position erreicht hat. In diesem Moment fluchtet der Filterstab 3 mit der Mündungsöffnung und kann frei aus der Aufnahme 2 in die Mündungsöffnung 67 bewegt werden. Die längsaxiale Bewegbarkeit eines Filterstabes 3 endet, wenn die Aufnahme 2 des rotierenden Förderers relativ zur Mündungsöffnung 67 die in Figur 4 gezeigte Position erreicht hat, in welcher ein Filterstab, der die Aufnahme noch nicht vollständig verlassen hat, zwischen der rotierenden Fördertrommel und der Mündung der stationären Förderleitung eingeklemmt wird. Die dabei auf den Filterstab wirkenden Kräfte sind so groß, daß der Filterstab abgeschert werden kann, wodurch entsprechende Teile des Filterstabes in die Förderleitung und weiter in die nachfolgende Produktion gelangen können, wo sie erhebliche Störungen verursachen können. Aus diesem Grunde ist vorgesehen, daß die längsaxiale Bewegung des Filterstabes aus der Aufnahme in die Förderleitung beim Abschuß überwacht und die Rotationsbewegung der Fördertrommel 1 angehalten wird, wenn ein Filterstab seine Aufnahme beim Abschuß nicht rechtzeitig verlassen hat.During the operation of the conveyor, the Firing a filter rod 3 from a receptacle 2 of the conveyor can begin when the recording is relative to the mouth opening 67 of the pneumatic delivery line that shown in Figure 3 relative position. At that moment, cursed the filter rod 3 with the mouth opening and can freely from the Recording 2 can be moved into the mouth opening 67. The longitudinal axial Movability of a filter rod 3 ends when the recording 2 of the rotating conveyor relative to the mouth opening 67 has reached the position shown in FIG. 4, in which a filter rod that has not yet completely left the recording has between the rotating conveyor drum and the mouth the stationary delivery line is pinched. The one there forces acting on the filter rod are so great that the Filter rod can be sheared off, creating corresponding parts of the filter rod into the delivery line and further into the subsequent one Production can get where there is significant disruption can cause. For this reason it is provided that the longitudinal axial movement of the filter rod from the inclusion in monitors the delivery line at launch and the rotational movement the conveyor drum 1 is stopped when a filter rod did not leave his admission in time at the launch.

Hierzu geben die beiden Initiatoren 54 und 56 ein Zeitintervall T (Figur 6) vor, in welchem eine Aufnahme 2 während der Drehung der Fördertrommel 1 mit der Mündungsöffnung 67 der Förderleitung so fluchtet, daß eine längsaxiale Filterstabbewegung in die Förderleitung möglich ist. Die Initiatoren sind auf die vordere Flankenfläche 69 der Stege 6 eingestellt. Wenn diese Flankenfläche 69 zum Zeitpunkt t1 von dem Initiator 54 erfaßt wird, was in Figur 3 dargestellt ist, bildet dieser ein erstes Positionssignal P1, welches anzeigt, daß eine Aufnahme 2 mit dem in dieser geförderten Filterstab 3 nun mit der Mündungsöffnung 67 der Förderleitung fluchtet und der Abschuß erfolgen kann. Wenn dieselbe Flankenfläche 69 zum Zeitpunkt t2 von dem zweiten Initiator 56 erfaßt wird, bildet dieser ein zweites Positionssignal P2, das anzeigt, daß die Aufnahme inzwischen soweit aus der Abschußzone Z ausgetreten ist, daß eine weitere längsaxiale Bewegung des Filterstabes nicht mehr möglich ist. Zwischen dem Zeitpunkt t1 des ersten und dem Zeitpunkt t2 des zweiten Positionssignals liegt das Zeitintervall T (Figur 6a), in welchem die längsaxiale Bewegung der Filter aus der Aufnahme in die Förderleitung möglich ist.For this purpose, the two initiators 54 and 56 specify a time interval T (FIG. 6), in which a receptacle 2 is aligned with the opening 67 of the conveying line during the rotation of the conveying drum 1 so that a longitudinally axial movement of the filter rod into the conveying line is possible. The initiators are set on the front flank surface 69 of the webs 6. When this flank surface 69 is detected by the initiator 54 at time t1, which is shown in FIG. 3, it forms a first position signal P1, which indicates that a receptacle 2 with the filter rod 3 conveyed therein is now aligned with the opening 67 of the delivery line and the launch can take place. If the same flank surface 69 is detected by the second initiator 56 at time t 2 , it forms a second position signal P 2 , which indicates that the recording has now emerged from the firing zone Z to such an extent that a further longitudinal axial movement of the filter rod is no longer possible . Between time t 1 of the first and time t 2 of the second position signal lies the time interval T (FIG. 6a) in which the longitudinal axial movement of the filter from the holder into the delivery line is possible.

Um zu überwachen, ob ein Filter in dem in Abhängigkeit von den Positionssignalen P1 und P2 der Initiatoren 54 und 56 von der Steueranordnung 53 vorgegebenen Zeitintervall T seine Aufnahme 2 tatsächlich vollständig verläßt und die Fördertrommel die nächste Aufnahme störungsfrei in die Abschußzone Z bringen kann, erfaßt der Sensor 52 (Figur 1), der dem Übergang von der queraxial bewegten Aufnahme 2 zum stationären Mundstück 22 der Förderleitung 21 zugeordnet ist, die längsaxiale Bewegung des Filters 3 beim Abschuß. Er erzeugt ein den Beginn und das Ende des Filterdurchgangs durch den Erfassungsbereich des Sensors anzeigendes Übergangssignal S, dessen zeitliche Lage und Dauer von der Steueranordnung 53 relativ zum Zeitintervall T geprüft wird. In Figur 6b und in Figur 1 ist der Normalfall dargestellt, daß der 3etrieb störungsfrei läuft. Die längsaxiale Filterbewegung aus der Aufnahme an dem Sensor 52 vorbei in die Förderleitung, die durch das Übergangssignal S angezeigt wird, liegt voll im Zeitintervall T; der Filter verläßt die Aufnahme vollständig, während die Aufnahme die Abschußzone Z durchläuft.To monitor whether a filter in the depending on the Position signals P1 and P2 of the initiators 54 and 56 from the Control arrangement 53 predetermined time interval T its inclusion 2 actually leaves completely and the conveyor drum Bring the next shot into the launch zone Z without interference can, the sensor detects 52 (Figure 1), the transition from the transversely axially moving receptacle 2 to the stationary mouthpiece 22 of the Delivery line 21 is assigned, the longitudinal axial movement of the Filters 3 at launch. It creates the beginning and the end the filter passage through the detection range of the sensor indicating transition signal S, its timing and duration checked by the control arrangement 53 relative to the time interval T. becomes. The normal case is shown in FIG. 6b and in FIG. that the 3 operation runs smoothly. The longitudinal axial Filter movement from the receptacle past the sensor 52 into the Delivery line, which is indicated by the transition signal S lies fully in the time interval T; the filter leaves the recording completely while the shot passes through the launch zone Z.

Die Figuren 6c und 6d zeigen die Signalverläufe im Störungsfall.Figures 6c and 6d show the signal curves in the event of a fault.

Wenn das Übergangssignal S des Sensors 52 nicht komplett im vorgegebenen Zeitintervall T liegt (Figur 6c), so heißt das, daß der Filter noch.im Übergangsbereich zwischen der Aufnahme und der Mündung 22 der Förderleitung 21 liegt, wenn die Aufnahme die Abschußzone Z verläßt (vgl. auch Figur 4). In diesem Fall gibt die Steueranordnung 53 ein Störsignal ab, das augenblicklich den Trommelantrieb 8 anhält und die Fördertrommel 1 zum Stillstand bringt, bevor der zwischen Trommel und Mündung der Förderleitung eingeklemmte Filter abgeschert wird und Filterfragmente in die Förderleitung gelangen. Gleich darauf steuert die Steueranordnung 53 den Motor 3 zurück, wodurch die Sendetrommel um einen kleinen Winkelbetrag zurückgedreht wird und den eingeklemmten Filter freigibt. Ist der Filter in Ordnung, kann er jetzt noch von der weiter durch die Aufnahme strömenden Förderluft in die Förderleitung 21 bewegt werden (Figur 6c), wodurch die Störung rasch behoben wird. Läßt sich der Filter nicht weiter fördern (Figur 6d), schaltet die Steueranordnung 53 die Ventile 61 und 62 um, schaltet also die Förderluft ab und die Rückblasluft durch den Anschluß 57 ein, so daß der Filter in die Aufnahme zurückbewegt wird. Der Dichtklotz 23 wird in die abgesenkte Wartungsposition 58 bewegt und seine Dichtfläche 24 mittels eines Druckluftstroms aus der Reinigungsdüse 59 freigeblasen, wobei die ausgeblasenen Filter in einen nicht gezeigten Sammelbehälter abgeworfen werden. Die Betätigung der Dichtklotzantriebe 38 und das Umschalten des Reinigungsluftventils 63 erfolgen ebenfalls in Abhängigkeit vom Störsignal durch die Steueranordnung 53.If the transition signal S of the sensor 52 is not completely in predetermined time interval T (Figure 6c), it means that the filter is still in the transition area between the recording and the mouth 22 of the delivery line 21 is when the Recording leaves the launch zone Z (see also Figure 4). In in this case, the control arrangement 53 emits an interference signal which momentarily stops the drum drive 8 and the conveyor drum 1 before the drum and Clogged filter mouth of the delivery line is sheared and filter fragments get into the delivery line. Immediately afterwards the control arrangement 53 controls the motor 3, whereby the Transmitter drum is turned back by a small angle and releases the jammed filter. If the filter is OK, he can now continue from the recording flowing conveying air can be moved into the conveying line 21 (Figure 6c), which eliminates the problem quickly. Let yourself if the filter does not convey any further (FIG. 6d), the control arrangement switches 53 the valves 61 and 62, so switches the Conveying air from and the blow-back air through port 57, so that the filter is moved back into the holder. The sealing block 23 is moved into the lowered maintenance position 58 and its sealing surface 24 by means of a compressed air flow from the Blown cleaning nozzle 59, with the filter blown out be dropped into a collecting container, not shown. The Actuation of the sealing block drives 38 and switching the Cleaning air valves 63 are also dependent from the interference signal by the control arrangement 53.
